Verified step by step guidance1
Analyze the structure of suvorexant provided in the image. Identify the stereocenter marked with the (R) configuration.
Recall the Cahn-Ingold-Prelog priority rules to assign priorities to the substituents attached to the stereocenter. Assign priorities based on atomic number and connectivity.
Orient the molecule so that the lowest priority group is pointing away from you (into the plane of the paper). This is typically represented as a dashed bond.
Determine the order of the remaining three substituents (1, 2, 3) around the stereocenter. If the sequence is clockwise, the configuration is (R); if counterclockwise, it is (S).
Adjust the substituents or bonds in the structure to ensure the stereocenter matches the (R) configuration as specified in the problem.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Chirality
Chirality refers to the geometric property of a molecule that makes it non-superimposable on its mirror image. Molecules that possess chirality have at least one chiral center, typically a carbon atom bonded to four different substituents. This property is crucial in organic chemistry as chiral molecules can exhibit different biological activities, making it essential to determine their (R) or (S) configurations.

What is chirality?
R and S Configuration
The (R) and (S) designations are used to describe the absolute configuration of chiral centers in a molecule. The Cahn-Ingold-Prelog priority rules are applied to assign priorities to the substituents attached to the chiral carbon. If the sequence of priority decreases in a clockwise direction, the configuration is (R); if it decreases counterclockwise, it is (S). This classification is vital for understanding the stereochemistry of compounds.

Stereoisomerism
Stereoisomerism is a form of isomerism where molecules have the same molecular formula and connectivity but differ in the spatial arrangement of atoms. This includes both geometric isomers (cis/trans) and optical isomers (enantiomers). Understanding stereoisomerism is essential in organic chemistry, particularly in drug design, as different stereoisomers can have vastly different pharmacological effects.

Textbook Question
Natural products are organic compounds produced by living organisms, including plants, fungi, and animals. Often referred to as secondary metabolites because they are not required for survival of the organism, natural products have found broad utility as drugs themselves or as lead compounds used in the development of medicines. One such example is paclitaxel, which has been used as a cancer drug. Paclitaxel is isolated from the yew tree, where it is produced as a single stereoisomer (shown). Based on its structure, how many stereoisomers are possible for paclitaxel?
